METER-SEAL.

Specification of Letters Patent.

Patented Aug. 21, 1917.

Application filed March 23, 1917. Serial No. 156,823.

America, and a resident of East Orange, in.

the State of New Jersey, have invented certain new and usefulImprovements in Meter- Seals, of which the following is a specification.

This invention relates to seals adapted to secure meters and similarinstruments within their metallic cases against unauthorized tampering.

The object of the invention is to provide a simple and efficient deviceadapted to bear a serial number and other appropriate identificationmarks, which when used with ordinary sealing wax combines with thelatter to produce a durable and effective seal not readily injured byordinary handling.

One sheet of drawings accompanies this specification as part thereof inwhich like reference characters refer to like parts throughout. Figure 1represents a meter or other instrument casing sealed by this improvedseal; Fig. 2 shows a face view of the seal before use; Fig. 3 is asectional side view taken on the line ww of Fig. 2; Fig. 4 is a top viewof the seal.

Referring to the drawing, the seal comprises a half hollow ring apressed from sheet metal and a metal tag b either integral with the ringor fixedly attached to one side thereof in the plane of the ring andadjacent to the flat side of the same. This tag is fiat and adapted tobe embossed with a serial number permanently identifying it and thering. 0 in Fig. 1 represents sealing wax applied to the casing to besealed within and protected by the ring a, X represents the top of thecasing, Y the main body of the casing and ZZ the joint of the casing tobe sealed-here shown soldered and sealed.

In operation the top of the casing X is soldered to the body Y at thejoint ZZ and the sealing half-ring a is then soldered over the joint ZZ.Sealing wax is then melted and applied within the ring and over thejoint ZZ with a suitable die showing date and party applying the seal.

It will'be noted that the half ring is identified by the markings on itstag and itself operates to protect the wax seal from acci dental injurybesides adding strength and additional security to the joint. The termhalf ring as used throughout this specification and in the claims is tobe understood as meaning a ring of substantially semicircular crosssection, having one broad surface flat.

The half hollow feature of the ring is not essential. but follows thecommercially advisable practice of stamping the half ring from sheetmetal. The invention does re quire a half ring with the resultantflattened side adapted to being soldered over the joint to be sealed,and having sufficient thickness to protect the wax seal impressed Withinit.

Having thus described my invention, I claim:

1. A seal for meters and the like, comprising a metallic half ring ofsubstantially semi-circular cross section having one broad surface flatand also having a projecting metallic tag integral therewith, adapted tobe used in combination with sealing wax as and for the purposesspecified.

2. A seal for meters comprising a half hollow ring of pressed sheetmetal of substantially semi-circular cross section having one broadsurface flat and also having a metal tag fixedly attached thereto,adapted to be used in combination with sealing wax as and for thepurposes specified.

3. A seal for meters having in combina tion a half ring of suitablemetal, a metallic tag attached to one side thereof adapted to beembossed with a serial number, said ring being adapted to be soldered onits fiat side over the joint to be sealed and sealing wax impressed oversaid joint and within said ring, all substantially as specified.
